Levart [38]

Answer:

When the input is 4, the output of f(x) = x + 21 is 25.

Step-by-step explanation:

The given function is

$f(x)=x+21$

Here, x is input and f(x) is output.

We need to find the output of the given function f(x) if the input is 4.

Substitute x=4 in the given function.

$f(4)=4+21$

$f(4)=25$

So, the output value is 25.

When the input is 4, the output of f(x) = x + 21 is 25.

The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

NeX [460]

Answer:

0.674

Step-by-step explanation:

If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is

$\bf f(x)=\frac{1}{25}e^{-x/25}\;(x\geq 0)$

and its cumulative distribution function (CDF) is

$\bf P(X\leq t)=\int_{0}^{t} f(x)dx=1-e^{-t/25}$

So, the probability that X is less than 28 minutes is

$\bf P(X\leq 28)=1-e^{-28/25}=1-e^{-1.12}=0.674$
